VEHICLE-HUB.

SPECIFICATION forming part of Letters Patent No. 334.508, dated January 19,1886.

Application filed September 1, 1 885. Serial No. 175,878. (No model.)

To all whom it may concern:

Be it known that I, DANIEL BOOKWALTER, a citizen of the United States, and a resident of Miamisburg, in the county of Montgomery 5 and State of Ohio, have invented certain new and useful Improvements in Vehicle-Hubs, of

which the following is a specification.

This invention relates to improvements in vehicle-hubs, the object being to provide a metallic casing for the customary wooden hub, which will greatly strengthen and at the same time protect it without detracting from its appearance. 7

With these objects in view my invention consists in certain features of construction and combination of parts, which will be fully described in connection with the accompanying drawings, and particularly referred to and pointed out in the claims.

Referring to the drawings, in which like parts are represented by similar referenceletters wherever they occur- Figure 1 is an axial section of a hub pro- Vided with my improvements. Fig. 2 is a similar view of the finished hub having the metal casings,which are placed over opposite ends of the hub interlocked with each other. Fig. 3 is a similar view, drawn to full size, of a portion of a hub with the casings represented in Fig. 2 as they are first placed upon the hub and before the overlapping portion is compressed upon the other.

The hub A is of ordinary construct-ion, except that it may be made somewhat smaller than the customary wooden hub.

B is a light metallic casing or shell, which closely fits over the hub, being pressed on over the rear end. It is provided with sockets b, which are preferably the fullsize of the spoke- 40 shoulder. These sockets register or come immediately above mortises a, which receive the tenons of the spokes O. This shell is first pressed over the hub A from the rear end, and it has a rahbet, 1), formed in it to receive the inner end ofa lightmetallic shell, D, which is forced onto the hub from the opposite or outer end ofthehub. The interior of the shell 13 is slightly smaller than the diameter of the hub, so that some force is required to press it to its place, as shown in Fig. 1, and the inner end of the shell D is also made to snugly fit the portion of the outer hub which it incloses, and its inner end of the full diameter of the overhanging lip 12 of the part B, so that when the two parts are forced together in opposite directions over the hub by suitable dies, as shownin Fig. 1, they will firmly interlock, and in forcing them to this position the wood is slightly compressed, so that there is no danger of the parts becoming loose.

In the form shown in Figs. 2 and 3the metal on the inner end of the part D is increased in thickness, and the overhanging fiangeb is straight, so that when the two shells are forced upon the hub they appear as in Fig. 3. After they have been thus forced to their place the overhanging flange b is compressed down upon the part D, thus firmly interlocking the parts of the shell together. The two shells B and D in either case form a complete metallic 7o casing for the hub. They are preferably made of malleable metal, and after they are forced onto the hub and interlocked together, as described, they are put into a lathe and finished off upon the outside, so that the hub has the strength and appearance before it is painted and finished of a solid metal hub, and after it is finished has the light neat appearance of the ordinary wooden hub. The shell D may of course extend to the front end of the hub; but I prefer to leave it, as shown, back of the end, so as to leave room for the plated or ornamental point-band.

I am aware that it is not new to incase wooden hubs with a band adapted to encircle the central portion of the hub and provided with spoke-sockets, and to inclose the innerend of the hub with a shell, which is forced onto the hub from the same end as the central band, its inner end passing under the end of the central band; but in this form it is not practicable to incase the front end of the wooden hub with metal without giving it such shape as would render it clumsy and unsalabio; and I am also aware that it is not new to incase hubs with two metal bands put on from each end, but not extending to the spokesockets, and separate flanged bands in the center of the hub to form supports for the spokes, and hence do not claim these.

What I claim as new, and desire to secure by Letters Patent, is

1. In a vehicle-hub, the combination, substantially as specified,oftlie hub-body A,tapering ateach end from the central portion,and the two-part metallic shell 13 D, incasing said hub, the said part B extending from the end of the hub beyond the center and provided with spoke-sockets, and the end of the case which extends beyond the spoke-sockets provided with a flange formed by the internal rabbet to overlap the inner end of the part D, which part is forced onto the hub from the opposite end.

2. The combination, substantially as speci- DANIEL BOOIUVALTE R.
